Patented July 12, 1932 UNITED. STATES PATENT OFFICE WILLIAM E. A. PIPHERAND ALVIN n. PIPHER, PARKEBS A DING. PENNSYLVANIA OIL Aerrnron'Application filed July 18, 1931. Serial No. 551,806.

This invention relates to an. oil agitator As is well known to thoseskilled in the art more oil can be bailed from an old well than can beobtained by pumping. This is due to the fact that the bailer, when movedup and down through the oil stirs it thor- 19 oughly and washes therock, thereby allowing the oil to flow more freel into the well. As ameans for increasing ow some operators have drilled small holes part waythrough the ball in the standing valve so that when the hole in the ballturns to the right position it allows a jet of oil to shoot back intothe well so as to stir the oil in'the well. At best this method is veryunreliable. It is an object of the present invention to provide apositive agitating means for the oil, said means being actuated by themovement of a valve which, in turn, is operated by the suction of oilthrough the working barrel.

Another object is to use an agitating device located outside of thetubing where it can readily churn or agitate the oil and keep the rockfree from paraffin.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combi nation andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings the pre-' ferred form of the invention hasbeen shown.

In said drawings:

Figure 1 is an elevation of the device attached to a working barrel inplace of the usual perforated tubing anchor.

Figure 2 is an elevation view at right angles to Figure 1. V

Figure 5 is an enlarged section on line 5 5, Figure 1. v

Figure 6 is an enlarged section on line 66, Figure 1.

Referring to the figures by characters of reference, l designatesthelower end of a working barrel engaged by a coupling 2 which supports thetubing 3 forming the body portion of the present invention. A head 4joins the tubing to the sleeve and has a central "1 countersunk bore 5about which is arranged a series of small openings or ports 6. The spacebetween headeand working barrel 1 forms a Valve chamber 7 in sleeve 2.The lower end of tubing 3 is engaged by collar 8 which supports ,aspacing ring?) loosely mounted on the tubing; A pin 10 limits themovement of this ring. Another spacingringll is carried by head 4beneath sleeve .2. 1 V

. Longitudinal slots 12 are formed in the tubing 3 and extending looselythrough them is a diametrical cross bar 14 the ends of which arefastened to an agitating ring 15 slidable spring 16 extendinglooselyaround tubing 3 and slidable thereon.

-A flat'valve 17 normally closes the ports 6. A rod 18 is secured at itsupper end-to this valve and extends downwardly through bore ball 14:. j

The tubing is adapted to be substituted for the perforated tubingusually attached to the the alternate or; upstrokes of the working valve(not shown) the oil will be sucked through slots 12 and upwardly throughports 6, at the same time lifting .the flat valve 17 Thus the bar 14 andring Will be elevated along tubing 3 and correspondingly move the spring16. When the suction ceases and the valve 17 drops the rod 18 and theparts connected thereto will also drop.

Spring 16 and ring 15 will-act to churn the oil and keep the rock washedthoroughly and while means other than a spring could be used as anagitator, it is preferred to employ a spring because it vibrates morereadily and;

During" on tubing 3. Thisring supports a coiled 5. The lower end of therod is attached to thus acts better as an agitator than would rigiddevices.

If preferred a flood hole 19 can be provided in head 4 although this isnot necessary.

Whatis claimed is: I 1. An oil agitator for attachment to the lower endof a working barrel, including a tubing having ports at its upper endand a slot in its wall, a valve normally closing theports and liftableby suction in the. working. barrel, an agitator slidable along theoutside of the tubing, and a connection between'the Valve and agitator,said connection working in the slot.

2; An oil agitator for attachment to the I lower end of a working barrelincluding a tubing having a port in its upper end, a valve normallyclosing the port and liftable by suction in the working barrel,"anagitator operated'by said valve, said agitator including a ring slidableon the tubing, and a connection between the'ring and. valve, said tubingbeing'slotted for the connection. 7

An oil agitator for attachment tothe lower end of a working barrelincluding a tubing having a port in its upper end, a valve 1 normallyclosing the port and liftable by suction in the working barrel, anagitator operated by said valve, said connection including a ring, a.cross bar connected thereto and slidable. in the tubing, a rodconnecting the bar and valve, and anagitatoron the ring and tubing.

4:. An oilagitator for attachment to the lower end of a working barrelincluding a tubing having a port in its upper end, a valve normallyclosing the port and l iftable by suction in the working barrel, anagitator operated by said valve,'said connection including a ring, across bar connected thereto and slidable in the tubing, a. rodconnecting the bar and valve, and an agitating spring supported by thering and slidable on the tubing.

5. A structure for attachment to the lower end ofa working barrel, asuction operated valve, and oil agitating means operated by the valvefor working between said structure s and the side wall of a well.

Intestimony that we claim the foregoing as our own, we have heretoaflixed our signatures.
